I dunno - as much as I hate micro-DLC I find that if I wait till Steam offers the usual deep discount on all DLC released - it actually costs me far less than the old (and more civilized) expansion pack model.

I just picked up all the DLC for Warhammer Ret. 40K for like 10 bucks - and individually they were almost over $70. Now I have it all - like a proper ex-pack - and on the cheap.
